HonwArna 'HEATER To all whom-'t may concer/n.:

Be itknown that LEDNA J. SIDBURY, a citizen or the United States,residing at `New York, in the county of New York and AState of New York,haveiiivented new and useful `Improvements "in Hotl/Vatr Heaters, of

which the following is aspeciication.

This invention is hot water heater,

`more particularly adapted for domesticuse,

wherein the refuse such `as fis accumulated in the household maybeburned "to furnish the heat in addition tothe other fuel.,

The invention contemplates the 'use of `a down-'draft type or furnacehavinga water jacket to which may befconnected suitable service pipes`and the usual household boiler. 011e objectof the invention istoprovide for the burning of the refuse in a convenient furnace 'andutilizingtheheat of such burning for the heating ol` waterv for domesticpurposes. j i

The invention broadly stated,"comprises a Vdown-draft furnace that;isprovided with` a `water jacket, a llue'fleading `from the com-"bustion space, inletand outlet pipes connecting the water jacket, andmeans toutili'ze the water after heating in a domestic boiler orsuitable radiator. i j

One practical form of construction will be described and illustrated inthe accom n panying drawing, in which Figure 1 is a vertical sectionalview of the heater connected 'to a household boiler;` and FigtQ is anelevation of the heater connecte'd to a radiator.

*Inthe embodiment shown in thesaccompanyingf drawing, the heater maybecylindrical'in Jform and is provided with the spaced apart verticalwalls 5"and 6. The space between the walls 5 and 6,indi'cated :at 7provides a water jacket which entirely surrounds the iire pot inwhichrthe fuel 8 is disposed. At some convenientpoi'nt adjacent thebottom wall 9 of the heater, there is a hand hole `which extends intothe lire pot and is closed by means of the cover 10. This cover 10 maybe secured Vin any usual manner to'theheater, so'as to =prevent theashes and. burned `product from fallin out accidentally. `As shown, thehand `ho e 11 .passes through the walls 5 and 6,but is not 1ncommunication therewith, as the hand hole is surrounded by a suitableconnecting piece indicated at 12, which being formed integrally with thewalls prevents leakage of water.

` Specification of Letters Patent.

Vthe cover 14a;

Patented Dec. d, .1917.

Appnaabii mediaan 1s, 1917; serial No. 161,306.

To 'support the 1heater from lthe floor,` the legs 413 may beeinployed,which maybe of any usual or customary type of construction suitable for"this purpose. IThey may be relncvably secured to thebottonr wall 9, if

`so desired. As shown, itis preferred to construct the walls 5 and 6'and the bottom wall 9` a unitary structure, that is to say being castin one piece in one operation, although for more practical purposes thebottom wall 9 may be formed as a head that maybe secured to the walls 5and 6 in the usual or customary manner.

The heater is closed by means of a top 14, which as 'shown is providedwith a centra-l opening that is closed by means of the cover 15, and thefuel opening thatis closed by Secured tothe under side `of the top 14and adj acent the centralopening is afconical draft member 16, which hasat its lower depending end a cylindrical sleeve portion 17 to provide asliding and adjustable connection with the down-draft air tube 18. 7Themember 16 is provided with a flange 16a so that it may be secured to the`under side of the top plate or wall 14. yThe draftair tube 18 may beraised and lowered in accordance with the amount of fuel within-the firepot of the heater. This will permit of the introduction of airA at thebest point for burning the fuel.

The cover 15 may be provided with suitable openings that may be closedor; opened I'as the requirements of combustionl necessitate. Thus thetop 15 may be employed as a damper, although if desired it may be madesolid and removable from the opening. At another point in the top thereis another opening indicated at 19, that is surrounded by a 'collar 20,to which is secured a llue pipe21 having a suitable damperQQ` disposedtherein. This flue pipe Q1 communicate'swith the combustion spaceindicated at A. i i

The top 14 is provided with suitable annular flanges indicated at 23 and24. These flanges 23and 24 Vare adapted to coperate with the walls 5 and6 and be secured thereto in any convenient or workmanlike manner.

The manner of fitting this top upon the side j walls will be such that awater-tight joint" point oit' attachment to the top wall or boiler ltand the water jacket 7 is indicated at 26. The outlet pipe 25 isconnected to a boiler 27 in any suitable or usual manner, the point ofattachment being shown in Fig. l at 28.

Communicating with this boiler are suit'- able Vservice pipes indicatedat 29 and 30, which serve to permit watertovbe fed to the water jacket7, and also tobe withdrawn from the boiler 27. Secured to the bottom ofthe` boiler 27 is an inletpipe 31 that has a suitable connection withthe wall 5 so that it may communicate directly with the water Ijacket 7to ll said jacket with water, the

point ofconnection being indicated at 32,

and this 4connection may be of the usual or customary type. The boiler27 is supported upon the usual or customary stand indicated at 33, whichhas a foot plate'e resting upon the floor indicated at 35.

In Fig. 2 there is shown A a modification which adapts the heater toheat `water for a f radiating system, one of the radiators being shownat 3G. In this figure, the inlet pipe is indicated at 31, andthe outletpipe at 25. These two pipes serve to connect the heater @and `itsrwaterjacket to the service pipes. VThe pipe 37 connected with the upperportionof` the water jacket serves to direct the heated `water to thetop of the radiator 36. A valve 38 may be disposed in this .pipe so asto restrict the passage of the heated water to the radiator. f

. The lower portion of this radiator 36. is connectedto the lowerportion of the water jacket by means of an inlet pipe indicated at 39.lThe pipe 39 may also be provided with a valve if so desired, the valvebeing indicated at 40.

As shown in this figure, the cover l0 of Fig. l may be formed as a doorhaving a hinged connection with the wallV 5, the hinged connection beingindicated at 41. To maintain the door in closed position, a latch 4-2may be employed, which is provided with a suitable keeper indicated at43.

While the device has been shown as being more particularly adapted forheating waj ter, the same may be utilized for the produced for householduse,

ltion of steam with slight changes in form 'and construction, while theessential or main details remain the same. The change may be effected bythe employment of addithe supply of ,water tothe jacket 7. As thesemeans do not come within the scope of this invention,

they are not shown or described. f

As this device is more particularly adaptthe heater may be employed forburning refuse, such as newspapers and garbage in connectionwith Asolidfuel.- This utilization of the `waste productsj of the house will enablethe heater to be operated in an economical manner. melon ,of the.down-draft tube typeivill enincluding1 an air-tube and The proable theuser to increase the rate of 'combusvtion oi' the fuel with very littleeffort. In

bustion and proceed upward j throungh the fuelv and by means of theoxygen supplied thereto will increase the rate of combustion to thedesired point, and the Vmaximum amount of heat unitswill be evolved,` `i

The provision of the waterV jacket "surrounding the lire boX andthecombustion space maintains the water in the closest contact with theheat emitting substances, and the combustion chamber A being lilled withheated gases communicates its heat tothe wall 6.` The water jacketj 7,being filled with water, abstracts the heat'therefrom, and is heatedthereby. ,j j j -A The down-draft tube type of heater is adapted toproducevan intense .tire and' a rapidrate ofcombustion `by reason oi itsconstruction, and from this construction a large amount of .air isconsumed producing a large number of heatunits. The water disposedwithin the jacket 7 is Vvvery quickly heated, and after being heatedpasses tothe boiler 14 in a more or lessnatural manner so that there isa constantcirculation within the jacket 7 by the water. Y l, f

Minor changes in the` form, proportions,

Vand details of construction maybe resorted to without departing fromthe spiritof the invention 0r claims.
